Additionally, if you are interested in learning Python, it is important to understand the basics of Java programming as well.

What is Core Java?

In learning Java programming language, it may be hard to understand the basic terms of Java: Core Java and Advanced Java. So before digging into the Java tutorial concept, little do you know about core Java and Advanced Java? Understanding the basics of HTML can also be helpful in learning Java, as HTML is used to create the user interface for Java applications.

  • Core Java
  • Advanced Java

Core Java: Sun Microsystem uses the term Core Java. A basic version of Java refers to the collection of libraries rather than the object-oriented programming language. It is a standalone Java application that covers various topics like the OOPS concept, operators, data types, wrapper classes, collection & and exception handling. JavaFX is a popular library for creating graphical user interfaces (GUIs) in Java. An algorithm is an important part of Core Java, as it helps in solving complex problems efficiently.

Advanced Java: Advanced Java is also one of the parts of the Java programming language. But you can even say that the adventure is everything beyond Core Java. Advance Java, mostly the API, is defined in Java Enterprise Edition (JEE), including servlet programming and web Services with java ee. It combines web and enterprise application development, following client and server architecture. With the increasing importance of the internet, knowledge of Advanced Java , including regex, is becoming more and more crucial for developers.
